Given numbers are 662,662,931,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 662,662,931,645 is 397527690.
Find LCM of 662,662,931,645 with Prime Factorization
2 | 662, 662, 931, 645 |
331 | 331, 331, 931, 645 |
1, 1, 931, 645 |
Multiply the prime numbers at the bottom and the left side.
2 x 331 x 1 x 1 x 931 x 645 = 397527690
Therefore, the lowest common multiple of 662,662,931,645 is 397527690.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
662 x 662 x 931 x 645 = 263163330780
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
662 : 1, 2, 331, 662
662 : 1, 2, 331, 662
931 : 1, 7, 19, 49, 133, 931
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,662,931,645, is 1.
Now, the common factors can be found like this.
662:2x 331
662:2x 331
931:7x 7x 19
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 331 = 662
Therefore, the value for common factors is 662.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 263163330780/(1x662)
LCM = 263163330780/662
LCM = 397527690
Thus, we can understand that the LCM of 662,662,931,645 is 397527690.
